Diagnostics of medium voltage and high voltage circuit breakers
Kapalla, Alexej ; Šimek, David (referee) ; Dostál, Lukáš (advisor)
This semestral work is about high voltage switchgears and their diagnosis. In this work there is part about history of HV switchgears and their dividing. Next part of this work describes diagnostic of HV switchgears VD4 24 ABB and AEG S1-245. In case of HV breaker VD4 there was provided diagnostics of new VD4 and used VD4. The measured values are then compared in the work and the influence of usage of breaker is presented according to his parameters. This work describes measurment of resistance of main contacts, insulation states.

Diagnostics of medium voltage and high voltage circuit breakers
Kapalla, Alexej ; Šimek, David (referee) ; Dostál, Lukáš (advisor)
This bachelor work is focused on medium-voltage and high-voltage circuit breakers and their diagnostics. The thesis presents the history of HV circuit breakers and their main division. Subsequently, the relevant standards are listed in the work and diagnostics of the MV circuit breaker VD4 and the HV circuit breaker S1-245 from AEG is performed. In case of the VD4 circuit breaker, a new and used circuit breaker was diagnosed. The measured values are then compared and the impact of usage is shown. The work describes the measurement of main contact resistance, insulation resistance, closing and opening times and vacuum quality.
